The Llangollen Railway is a volunteer-run heritage railway in Denbighshire, Wales, which operates between Llangollen and Corwen. The standard gauge line, which is 10mi long, runs on part of the former Ruabon - Barmouth GWR route that closed in 1965. It operates daily services in the summer as well as weekends throughout the winter months, using a variety of mainly ex-GWR steam locomotives as well as several diesel engines.
A 2+1/2mi extension of the railway has been built to complete the line to Corwen.
